Abstract
THE great aurora of January 25–26 last was observed and photographedfrom my nine photographic aurora-stations in southern Norway. From 18h16m until 6h 7m G.M.T., about 1,390 photo-graphs were taken, of which about 710 were successful. Among these, there are 95 sets taken simultaneously from two stations, 48 from three 14 from four, to determine height and position. Furthermore, about twenty spectra were secured. Besides this, I received about 180 letters with observations from different parts of Norway and about 20 from abroad. The working up of this extensive material will take a long time, but some preliminary results already obtained may be of interest.
